I won't directly answer 1 or 2, but here's my experience. For my job I was primarily using Elm and Go then for my new job it's been all Elixir. I thought I would miss Elm's compiler (Go, I do not miss). It's hard to explain, but I find that instead of thinking about what well-defined thing I'm reasoning about, it's about the flow of the data and what shape it happens to be in. In saying that, with structs and Ecto schemas, we pass those around primarily and pattern match on them too.
